Longhetti, F.\nZerbi\n(Osservatorio Astronomico di Brera, Merate, Italy)\nD. Lazzati (Institute of Astronomy,Cambridge, UK)\nP. Severgnini (Osservatorio Astronomico di Arcetri, Firenze, Italy)\n\nWe have obtained twelve 540-second dithered images in the Rc (Bessell)\nband centered on the position of  GRB 990705. These images have been\nobtained  from  20th to 28th December 2000 at the ESO-VLT UT1 telescope\nwith FORS1 as a part of a survey of host galaxies (Saracco et al. 2000;\nProg. ID: 66.B-0539(A)).\n\nObservations have been carried out under seeing conditions of 0.6-0.7\narcsec.\nThe limiting magnitude reached on the final coadded image is Rc=26.6\n(3 sigmas within the seeing disk).\nWe confirm the presence of a late-type (Sc) galaxy located at the\nposition of\nGRB 990705 as previously found by Holland et al. (2000; GCN #753).\n\nWe measure a magnitude Rc=22.2(+-0.1) (galactic extinction A(R)=0.2)\nwithin an aperture radius of 2 arcsec.\nConsidering the V-band aperture magnitude obtained by Holland et al.\n(GCN #753) we estimate for the host galaxy a color V-Rc=0.6(+-0.2).\nGiven the large uncertainty in this estimate, such a color is\nconsistent with that of an Sc galaxy  at redshift z<1.3.\n\nThis message can be cited.\n\n\n--\nPaolo Saracco\nOsservatorio Astronomico di Brera\nVia E.
